New data from Kaspersky shows a big increase in cyberattacks targeting Linux systems in 2025. The report highlights a growing number of exploits aimed at critical vulnerabilities, putting users and businesses at higher risk.
In the second quarter of 2025, the number of Linux users hit by exploits was more than 50% higher than in the same period in 2024. In the first quarter, the figure was nearly double compared to the previous year. Windows users also saw a rise, with a 25-point increase in Q1 and an 8-point jump in Q2.
Kaspersky found that 64% of all exploits in Q2 2025 targeted operating system flaws. That’s up from 48% in Q1. Attacks on third-party apps and browsers made up the rest. These exploits often allow hackers to take control of systems or steal data.
The report also noted a surge in new vulnerabilities. Over 4,000 CVEs are now being registered each month, compared to around 2,600 in early 2024. Many of these are used in advanced attacks that escalate privileges or install hidden tools.
Kaspersky recommends strong patch management, 24/7 monitoring, and secure testing environments to reduce risk.
This trend shows that Linux is no longer a low-risk platform. As threats grow, users must stay alert and keep systems updated.
